Why do you pronounce "stasistics" ? It's staTistics. :) sorry I couldn't help it. Extremophiles are not sofisticated. Many of them belong the the Archaea kingdom and are in fact rather simple and conserved (as in not evoluted). For lack of contact you really dont realise what is 100 years compared to the time scale of the Universe. And as long as you can't really approximate the probability of abiogenesis taking place, these 24 minutes of the video are pretty much wasted. There could be or there could not be life out there. All your useless thought experiments are just beating around the bush - we just can't know at this point if life is there.

Thanks for destroying most of my dreams for humanity. However i can only see two possible solutions with our current technology, first one is to build part of the future industries out space, second one is to make an space refrigerator to cold the Earth, any case is very hard 'cause out space the only way to dissipate energy is with radiation, wich is slow.

The argument should be asking, "Are we in a "Constructed" reality?" Simulation suggests an invalid inconsequential existence. We may be who we think we. If we are not then hopefully we will be better beings knowing what we learn here if we are Avatars. If we will be erased like a computer file in the end hopefully we will be remembered in some way, somehow.

YES ! The Human race is being observed by several VERY ancient and HIGHLY intelligent extra terrestrials ! Would love to know who they are, and where they're from ! But i guess they are peaceful, because If they wanted mankind gone, it would've already happened by now. They have had 1000s of years to utterly destroy us and wipe us out. I think that they are waiting for mankind to grow up and become more spiritual and in tune with nature, mind and soul ! Might be the ETs show themselves when we are reaching a Kardashev type 1. civilization, IF that ever happens !!! It's possible people, but we REALLY have to UNITE and be able to see through our politicians lies and grand illusions of total control over mankind. What i know for sure is the ETs are interested in our nukes/missiles ! They have demonstrated several times, how they remotely can activate or de-activate nukes/missiles ! And ofc, their aviation technologies and knowledge of physics are MANY years ahead of ours. It's simply fascinating !

An interesting hypothetical discussion, but the idea of a such a civilisation is, frankly, ludicrous. Harvesting ALL of the solar energy that would hit the planet? Really? That would mean the end of all other life on Earth, and we are part of it and totally reliant on it to an extent that none of us can remotely comprehend (mentally as well as physically). That's why Elon Musk's Mars crap is potentially so damaging, the more everybody gets behind it. And what would we do with all of that energy we've harvested, which had previously been used by all other life on Earth? What is actually the only thing worth striving for in life? Happiness and fulfilment. To understand what makes us truly happy one must understand how the organism has come to evolve to where it is now .You will arrive at the conclusion that it is being part of the nature on this planet and thus using our bodies and minds in that way which most perfectly makes us physically and mentally fulfilled. It's great to imagine and hypothesise. I for one had fun quantifying the practicalities and difficulties of the Halo (or should it be 'Boomerang') drive, but we must see things for what they really are and make sure Earth is protected from ourselves. I'm sorry to say this, but there is in reality, nowhere else out there for us. It's all too far away and, most importantly, wrong for us, but the fact that some of the matter created in the Big Bang has organised itself to such an extent that it has not only become self aware, but can think about such things is, in some ways, the crowning glory, the absolute pinnacle of the universe's achievements.

Replicating consciousnesses will not be very difficult at some point. There will be a base program that creates a self realized ability in that program to grow. Like we do as we age and gain knowledge. Remember consciousness does not require feelings. That is a human trait. I believe that matter is programmed at its base level and that this is an evolving virtual reality. Open world program. Great video.

There are really two questions: Is there life elsewhere in the universe? Is there intelligent life elsewhere in the universe. From what I have read about the subject, I am convinced that there is life out there, The experiments setting up artificial environments to see if live occurs spontaneously have been found to produce the molecules that are the basic to life. It appears that the molecules that are necessary for autogenous are those that form most readily. What is needed is for these basic life molecules to come together, form the next step in creating autogenesis. Additionally, there is the time factor; the longest running experiment of this type is approximately 70 years. It may have taken several million years for the right combinations of these molecules to agglomerate. As for intelligent life; that has a much much lower probability. Once there is some basic life form, on a planet, there will be some evolution to increasingly high form of life. One of the questions about the form of life is how did single-cell lifeforms evolve to form multi-cell life forms. However, once multi-cell life begins the same evolutionary processes will occur out there as it has progressed here on Earth. Many events had to happen here on earth at the right time to produce intelligent life, even to the equivalent of mammals. The necessary events could be volcanism, asteroid impacts, global climate change for whatever cause. From what we think we know, mankind appeared from arboreal creatures lick chimps that because of climate change or the availability of a sufficient diet, forced our precursors to come down from the trees and exist on a savannah. where their existence depended on the ability to prey on other animals without become prey for other animals. (lions....) Then there is the problem of the degree of intelligence that is reached. Much of Africa was still in the hunter-gatherer of crude form of farming while Europeans were building ships, wagons and ever more complex machines. The same is true of places like the Amazon basin, where up into the 20th century, tribes of hunter-gathers existed.

We are not alone. Hear me out. The universe is pretty young. Facts. And probably we are here because of the MOST ideal circumstances. The star, the distance to this star, our moon, the size of our planet, the size of jupiter, our position in the galaxy. Etc etc. All these factors are pretty special and rare. But it is not uncommon. The notion of we are here at the most early stage of the existance of the universe is a fact we cannot ignore. It is a strong argument. Not a weak one. I do agree it is a 'underbelly' feeling and not really a fact. But I won't ignore this. It is an important hint of how and why we have life and consciousness.

If your life feels pointless and you get sad when you think about how small we are, please don’t. Think of it this way, life has no real meaning. We’re part of a system that just exists and we can do whatever we so desire, of course without hurting others. We can give it our own meaning and instead of feeling small, it’s about feeling special and proud we are part of it. We tend to think “oh we’ll never get to know what’s out there” but we don’t think of it as whatever is out there won’t get to get to us, which means what we see or know about should be looked as our entire universe. What “they” can see or reach is their entire universe.
